  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

TE449 PCV Zipty Tunes

For the fuel maps, the numbers mean that percentage more (or less) fuel than normal. If you have 5 in there, it will inject the normal amount of fuel plus 5 percent of that more. Typically to stop flame outs you add more fuel in the low RPMs.
This is what I have and I can put around at idle with the front wheel locked up and not stall.

I don't tell the PVC what the voltages are, I reset it so 0 throttle is 0%, about .6 volts 100% is about 3.99.
I would suggest making the 0's in the zipty map from 1500 to 2500 5's. This seemed to work great for me.
I have not had a flame out since this adjustment. I believe it increases fuel that % over existing map,
I have map3 on the ECU. The zipty map seems very smooth and powerful on my bike but still
To lean for the FMF pipe, which I think Tinken is correct in that it does not have sufficent back pressure,
so to compensate, a little richer seems to really help. Try some settings yourself, but just don't go
Leaner to start, and only adjust from idle to maybe 3000 rpm, the zipty map is great after that,
Just my 2 cents and what has worked for me, my bike is running great.
 
waiting for my pcv to show up, so while waiting thought I'd ask the question, the handle bar switch to toggle between the two maps, does this only make /break a connection? and if so in theory any switch could be used?
going to put bike on a rolling road and start set up from there I think,should save some time as well.

Factory idle TPS voltage is 0.7v & will also make a small increase in idle mixture from a setting of 0.6v.
